RUOKER DAVIS, OF W OODROW, WEST VIRGINIA.

HYDRAULIC Moron.

Specification of Letters Patent.

Application filed August 5, 1907.

Patented May 26, 1908.

Serial No. 387,078.

To all whom it may concern:

Be it known that I, RUoKEn DAVIS, a citizen of the United States, residing at Woodrow, in the county of Morgan and State of West Virginia, have invented certain new and useful Improvements in Hydraulic Motors, of which the following is a specification.

This invention relates to hydraulic motors.

One object of the invention is to provide a motor embodying such characteristics that power may be generated for the purpose of driving apparatus or machinery at distant points.

Another object resides in the provision of a motor constructed and arranged to be driven by water power for the driving of machinery or ap aratus without steady employment of wor amen.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any of the advantages thereof.

In the drawings :Figure 1 is a longitudinal sectional view of my invention. Fig. 2 is a plan view with one-half in section. Fig. 3 is a transverse sectional view on the line a-a of Fig. 1.

Referring now more particularly to the accompanying drawings, the reference character 1 indicates a concrete or other base provided with a cavity 2 having a central depression 3 for the reception of the bearing lock 4 of the drive shaft 5, the bearing block 4 having a depression 6 for the reception of the reduced end 7 of the drive shaft 5 and to provide the annular shoulder 8 adaptin the concrete base 1 over the cavity 2, the drive shaft 5 working through an opening in this floor plate material 14. The center of the floor plate material 14 is preferably mounted upon a collar 14 carried by the drive shaft 5.

The reference character 15 indicates an annular water chamber for the reception of wa ter from a river, creek or other source by way of the feed pipe 16. This chamber 15 is preferably mounted upon the floor 14 and has an annular partition 17 adjacent its inner side to form separate compartments 18 and 19, the larger compartment 18 receiving the paddle blades 19.. These paddle blades are connected together in spaced relation by means of an annular rack 20 which is disposed directly over the partition 17 and whose teeth 21 are designed to mesh with the teeth of the oppositely disposed beveled gears 22, the beveled gears 22 being disposed in a smaller compartment 19 of the chamber 15. Every other one of the paddle blades 19 are pro vided with friction rollers 23, one at the top and bottom and on one side thereof. Obviously, each one of the paddle blades could be provided with friction rollers 23, if desired. These paddle blades 19 are rotated by the current entering the chamber through the feed pipe 16, the Water passing out of the annular chamber 15 into the circumscribing pipe 25 disposed at the lower edge of the annu ar chamber and communicating at 24 therewith and finally passing out through the waste pipe 26. Three corners of the paddles 21 are preferably strengthened or reinforced by the metallic or other annular lates 27, while secured to the fourth corner 0 each paddle 19 is the aforesaid circular toothed rack 20.

The oppositely disposed beveled gears 22 are mounted within the smaller compartment 19 of the water chamber, as before stated, upon shafts 28, each shaft 28 being journaled through the inner wall of the chamber 15 and supported at one end in the partition 17 and at its opposite end in the support 29. This support 29 is mounted u on the aforesaid floor 14 and embraces the rive shaft 5, there being upper and lower sets of bearing balls 30 and 31, respectively, between the drive shaft 5 and the su port 28 to insure easy and free rotation of t e drive shaft in said support.

Mounted upon each one of these shafts 28 ad jacent the support 29 is a gear 32 adapted to mesh with a gear 33 keyed to the drive shaft 5 above said support 29. If desired, suitable braces 34 maybe dis osed within the support 29 and the inner wall of the chamber 15.

Disposed near the periphery of the aforesaid gear 33 is a pin 35 to which is secured a pitman 36, whose outer end is provided with a pin 37 designed to engage a second pitman 38 to which latter may be secured a rod 39 for driving machinery or apparatus at a dis tant point. If preferred, the pin connec tion 37, the second itman 38 and the connection 39 could be ispensed with and power conveyed directly from the ear 33.

It will now be understoo that the paddle blades 19 are not mounted upon the shafts, but that they fit loosely between the walls of the chambers with certain of the blades having three sides provided with friction wheels 23 adapted to engage three walls of the cham ber to provide for an easy and free movement of the paddles under the influence of the water.

In the drawings it will be seen that the concrete extends up around the chamber and when water enters the latter through the feed pipe 16 it causes a rapid movement of the paddle blades 19. The movement of the paddles 19 in the chamber 15 causes the oppositely disposed gears 22 in the small compartments of the water chamber to rotate incident to their mesh with the circular rack 20 of the paddle blades. The rotation of these gears 22 transmits motion to the gears 32 adj acent the support 29, which latter gears being in mesh with the gear 33 carried by the drive shaft 5, causes rotation of the latter, and by reason of suitable driving connections cooperating with the gear 33 machinery or apparatus at a distant point may be driven.

By virtue of the concrete extending up around the chamber 15 means should be provided whereby access may be had to the lower end of the drive shaft, and to provide for access to the lower end of the drive shaft, I arrange a manhole 40 which communicates with a tunnel or main way 41 leading into a chamber 42, which latter has communication with the aforesaid cavity 2 at its center so that a person may readily inspect or remedy any possible defect in the machinery beneath the aforesaid floor 14.

That is claimed is 1. In a hydraulic motor, a base of cementitious material having a cavity provided with a central depression and an annular depression surrounding the central de ression, a floor above the depressions, a rive shaft passed through said floor and mounted in the central depression of the cementitious base, a support surrounding the drive shaft above the floor, a water chamber mounted upon the floor, the water chamber having an inlet and an outlet, paddle blades arranged in the water chamber, a gear upon the drive shaft, communicating gears between the paddles and the gear of the drive shaft, a balance wheel secured to said drive shaft and having its periphery working in the aforesaid circular depression, and connections operatively connected to the drive shaft for the operation of machinery at distant points.
